Damping Separator Element for Producing Delimiting or Protective Barriers

Abstract

The invention concerns a damping separator element for producing delimiting or protective barriers, for example for road traffic lanes or motor sports tracks. The element includes an elongated horizontal section and a cover, preferably made of flexible plastic material. The central reinforcement or hollow core, preferably made of metal, produced in the form of a flattened sheath and extended from one end to the other of the element, is housed inside the cover. The reinforcement provides a space between the cover and the central flattened hollow reinforcement, the space being filled or to be filled with a plastic foam such as, for example, a polyethylene foam.

1 . Separator and dampening element for producing delimiting or protective barriers used in roadways or motor sports tracks, the element comprising:
 a cover with an oblong horizontal section and middle portion, said cover having side walls and being formed from supple plastic material; and   a central reinforcing piece or hollow metal core, made as a flattened sheath, extending from one end to an opposite end of said element, the core having a space filled or intended to be filled by a damping material contained in said middle portion of said cover, said damping material being comprised of a plastic foam, said plastic foam being contained between said side walls of said cover and said flattened metal sheath.   
     
     
         2 . Separator element according to  claim 1 , said central reinforcing piece being hollow and being filled by a damping material. 
     
     
         3 . Separator element according to  claim 1 , further comprising:
 at least two stacked passages or orifices provided in each ends thereof, said at least two stacked passages being crossed, and   three stacked links being comprised of supple straps or flexible metal bands, connecting said element to other identical or similar separator elements to make a barrier.   
     
     
         4 . Separator element according to  claim 3 , wherein the central reinforcing piece has ends having one or several openings allowing passage of straps or flexible bands, or other supple or flexible links between vertical faces of said central reinforcing piece. 
     
     
         5 . Separator element according to  claim 3 , wherein the passages or orifices have ends, said ends being arranged at an upper edge of the element, another end near a base of the element, and a third one at mid height of the element. 
     
     
         6 . Separator element according to wherein said flattened sheath has ends laid out so as to allow attachment of said at least two stacked flexible metal ties, the ties being flat bands, allowing interconnection of separator elements. 
     
     
         7 . Separator element according to  claim 1 , wherein said cover is comprised of a non-frangible material. 
     
     
         8 . Separator element according to  claim 1 , wherein said cover contains at least one orifice, said orifice being placed in an upper wall of said cover, allowing injection of plastic foam. 
     
     
         9 . Separator element according to  claim 1 , wherein the reinforcing piece contains at least one orifice, said orifice being contained in an upper wall of the reinforcing piece, allowing injection of plastic foam. 
     
     
         10 . Separator element according to  claim 1 , the element having one convex cylindrical end and one concave cylindrical end, so that the wherein multiple elements can be abutted and interlocked with one another by sa adjacent ends forming an articulated interlocking or cylindrical articulation with the concave cylindrical end and the convex cylindrical end of adjacent separator elements. 
     
     
         11 . Articulated delimiting or protective barrier, used for roadways or motor sports tracks, said barrier comprising:
 a plurality of separator elements, according to  claim 1 , abutted and interlocked with one another through an articulated interlocking or cylindrical articulation, said separator elements being connected through at least two stacked supple or flexible links crossing, preferably, the passages or orifices made on the ends of the separator elements.   
     
     
         12 . Barrier according to  claim 11 , wherein the supple or flexible links are comprised of flat supple straps or flexible metal bands. 
     
     
         13 . Manufacturing process of a barrier of multiple separator elements, according to a separator element of  claim 1 , the process comprising:
 producing the cover and the reinforcing piece of each separator element in a plant, by rotary moulding; and   inserting supple damping material into internal empty spaces of the cover by injection on the sites where barriers are assembled and positioned, after the installation of supple or flexible links.
